Drone Photogrammetry for Surveys and Inspections

The Technique

Thanks to greater accuracy in drone navigation systems, computing performance and onboard photographic sensors, aerial photogrammetry by drone is highly performant and enables precision drone mapping, whatever the size and configuration of the terrain. Easier and cheaper than using imagery from a manned aircraft, drone photogrammetry provides professional-grade material for aerial surveys and inspections, enabling centimeter precision scaling, and measurement of distances, surface areas, and volumes.

Drone mapping from photogrammetry also allows us to easily create 3D models that can be rotated over 360 degrees on all axis to achieve a unique point of view of the photographed buildings, artwork, structures, quarries, bridges, roads, etc...

CamFly Films frequently uses aerial photogrammetry to gain higher zooming capabilities for surveyors in need of high-precision imaging of the inspected assets. Many industry sectors are using drone photogrammetry, such as:

Measuring Distances, Surfaces, Volumes, Elevation

From Left to right, different options to display and process the data, choosing to highlight volumes, relative height through colour cast or/and instant measurements, 2D map for a global vision, enabling powerful zooming to display tiny details, or even processing the map to create a 3D model, or tracing all roof sections of a building and create a report of all dimensions, areas, and pitches of the roof with a 99.4% accuracy.

The tools we use in drone mapping

CamFly films trust DJI drones for their stability and reliability, speed and battery life, featuring High resolution 20Mp camera sensors, shooting 4K video and Raw stills.

On the software side we use applications such as "Pix4D" or“Dronedeploy" for their high quality results, ease of use in the field for mission planning and execution, share and export capabilities to industry standard program such as AutoCAD.
